A Literal “New Spin” on Hybrid Milling/Grinding Machines

Mitsui Seiki’s Vertex hybrid machine borrows a jig grinder’s motion to complement high precision five-axis milling.

“The concept is to emulate jig grinding equipment,” says Robb Hudson, CEO of Mitsui Seiki USA, when describing a new family of Vertex five-axis hybrid vertical machining/grinding centers in booth 338519. Hudson explains that this concept is literally a “new spin” on milling/grinding hybrids, because the machines can apply a part spinning process that produces tangential planetary work spindle alignment, much like the U-axis motion of jig grinding equipment. Combine this with high speed 3+2 or full five-axis milling that is capable of 0.0003-inch (5.5 µm) precision, and the result is a machine that can carry out critical applications such as lights-out machining of die/mold, optical and tooling components, Hudson says.

The Vertex Hybrid G 55-5X machine on display has two larger siblings in the family, the 75-5X and the 100-5X. The show machine is demonstrating its capabilities with a combination of milling and grinding operations on a D2 steel plate, hardened and heat-treated to 60 to 62 HRC. A form milling tool is roughing and pre-finishing corner relief, followed by a form-grinding wheel for finishing. After a rounded triangular pocket is milled in the part’s center, a variety of grinding wheels form critical step features.

“We are claiming it has CMM-level precision because the engineered accuracy and rigidity meet volumetric calibration according to ISO10320-2 using the latest FANUC 3D volumetric compensation features, while enabling us to apply in-process 3D measuring capability traceable to the National Institute of Standards and Technology,” Hudson says. He adds that the machine’s structure, which features hand-scraped guideways, is configured to attain positioning accuracy in the X, Y, and Z-axes of 0.000040 inch (0.001 mm), ±6 arc seconds in the A axis, and ±4 arc seconds in the C axis.

“But the grinding aspect of this machine is the cool part,” Hudson says. “It’s not tacked-on. We have automatic, in-process grinding wheel dressing, size measurement and wheel calibration, plus an advanced thermal compensation system to enssure size consistency”

Hudson invites attendees to check out the machine for themselves. “They can see that this is not just a spin we put on the story.”

Another Bipartisan Buy America Bill Surfaces on Capitol Hill

Tammy Baldwin and Mike Braun in the Senate, John Garamendi in the House are sponsoring the Made in America Act.

We’ve got some good news for people who like proposed bipartisan legislation that would expand coverage for the domestic procurement rules that govern federal spending on infrastructure!

Sen. Tammy Baldwin – from Wisconsin, a Democrat – and Sen. Mike Braun – from Indiana, a Republican – have reintroduced the Made in America Act, which would identify “federal programs that fund infrastructure projects not currently subject to Buy America standards” and ensure “that materials used in these federal programs are domestically produced.” The bill would also require that the U.S. Department of Commerce, while setting the standards on which construction materials will be considered American-made, to ensure that their manufacturing processes support American jobs.

It has a sponsor in the House, too – Rep. John Garamendi (D-CA) – who is a longtime advocate for domestic manufacturing.

Garamendi has a long record of supporting legislation that would help generate more domestic manufacturing activity and the jobs that go with it, and this isn’t the first time this year that Baldwin and Braun have found themselves cosponsoring legislation like this. They were among a group of senators in January with their names on a bill that would tighten waiver requirements for projects subjected to Buy America rules.

Regarding today’s Made in America Act? It’s good legislation that will create more manufacturing jobs in the United States, which is why the Alliance for American Manufacturing has officially endorsed it.

You can find the Senate bill’s text here.

Anything I can do about my late order?

Republished by Plato

Published

Firstly, I know it’s a long shot. The manufacturer is in Sailkot, Pakistan. There are no contracts in place and the only type of documents I’ve received from this manufacturer are invoices. It’s a mistake I will never make again but I stupidly assumed that I could trust this guy after making a successful order with him in the past but it was a much smaller order.

I made an order for clothing roughly around 6 to 7 months ago and everything was going smoothly for around 1 to 2 months before he started taking days to reply and being very vague with his replies.

I know the clothes are being made because I will get the odd bad quality picture to show work is being done but the excuses this man has come out with is unbelievable. In this space of time some of his excuses have ranged from having family issues which have resulted in a divorce, having covid twice and even a middle man who was transporting my clothing from one vendor to another, just disappearing and stealing all of my clothes.

The ETA given at the start of the order was 7 to 10 days. After 7 months I’m nearly pulling my hair and feel completely helpless whilst my business fades away. There is a Chamber Of Commerce in Sailkot, Pakistan which is seems to be some form of authority over Manufacturers in that city. I’ve been in touch with them about my situation and they are willing to help but the manufacturer doesn’t seem fazed by this and actually told me I can get in touch with them but it’s not going to speed up my order.

I can’t go through the bank either because I paid through an app called Azimo.

Is there anything else I can do or am I just completely stuck here?

Thanks in advance.

Edit: I’m in England.
